Rafael Nadal defeated close friend Richard Gasquet for the 18th time to reach the US Open fourth round on Saturday as world number one Iga Swiatek made the last 16 for a second successive year. Four-time champion Nadal took his record over Gasquet to a perfect 18-0 with a 6-0, 6-1, 7-5 victory to stay on course for a 23rd Grand Slam title. World number one Swiatek downed unseeded Lauren Davis 6-3, 6-4. Swiatek came back from 1-4 down in the second set to reel off five successive games against the American who called a medical time out in the first set to have her blood pressure taken.
